When you added either a USB or a printer to your PC or Mac computer, you are supposed to get some documents printed. However, you may meet with USB not recognized, printer offline or so some similar issues like that. In order to resolve those issues, you can try below methods.
Fix: USB Device Not Recognized In Windows
Remove your Power Supply plug from PC.
Now Restart your PC.
Now connect your USB device to the USB ports. That's it.
After the USB device connected to your PC, then plug in Power Supply to PC.
Fix: Printer Offline Issues
Open the Start menu and click on the "Devices and Printers" icon. This will open a window with a list of the printers currently set up on your computer.
Double-click on the icon of the printer you want to change to online. The status of the printer will be shown as either "Printer: Ready" or "Printer: Offline."
Click on "Printer: Offline" and the Printer menu will appear. Click on "Printer" in the menu bar and uncheck "Use Printer Offline." This action will change the printer from offline to online.
Open System Preferences by clicking on the icon in the Dock.
Go to the Print & Fax control panel under the Hardware category.
Select the printer you want to take online from the list on the left side of the screen. Then click on the "Open Print Queue" button.
Click on the "Resume Printer" button at the top of the queue window to change the printer from offline to online.
Fix: Other Common Driver Issues
Open the device manager to diagnose the problem. You've obviously figured out that there's a driver error from the error messages every time you keep trying to complete a specific task, but the Device Manager can give you a better idea of what you're really looking at. Right click on the "My Computer" Icon on your desktop and select "Properties." On the Hardware tab, select "Device Manager."
Look for the yellow triangle. The Device Manager window will give you a list of all of the devices connected to your computer. Problematic devices will have a yellow triangle next to their name in the left column.
Right-click on the problematic device and then select "Properties." The Properties window should have tabs at the top. Under the "Resources" tab, check "Resource Allocation" and "Modify Resource Settings" to stop driver conflict errors. Select the "Update Driver" button and then install updates if the driver is outdated.
Uninstall the driver if the driver is completely corrupted. Reinstall after the driver has been removed. If you end up with a faulty driver, restore the original by selecting the "Roll Back Driver" button.
Use the Recovery Console if the Device Manager method does not work by Inserting the Windows installation disk and restarting your PC. Select R on the Welcome screen and login (you must be an administrator). Type in "CD Windows\system32\drivers" and select "Enter."
Continue in the Recovery Console mode and type in "Ren Driver_Name.sys Driver_Name.old," hit "Enter" then type "copy CD-Drive:\i386 Driver_Name.sys" and press "Enter" again. This will copy the original driver to the drivers folder. Once finished, exit Recovery Console, take the CD out, and restart your computer.
